Node:Lists, Next:Vectors, Previous:Pairs, Up:Compound Data Types
A very important data type in Scheme--as well as in all other Lisp dialects--is the data type list.1
This is the short definition of what a list is:
Strictly speaking, Scheme does not have a real datatype list. Lists are made up of chained pairs, and only exist by definition---a list is a chain of pairs which looks like a list.
